[OSGeo-Discuss] Does rasdaman CE solve an open source geospatial problem?

Sat May 21 09:36:02 PDT 2016

I think OSGeo should stay out of the business of weighing in on how companies decide to commercialize technologies, so long as they respect the licensing terms.

We and many companies use MapServer for instance at the heart of our proprietary stacks, which is simply another flavor of the open core model.

The more important issue here is whether the structure of a project's licensing and PSC provides a commercial advantage to one company over any other.

The concern I have with the benevolent dictator model in discussion here is that reasonable advancements members of the PSC may want to pursue for the project that may erode from the commercial interests of the benevolent dictator could be denied, and that doesn't feel like a fair playing field for the PSC to operate in, or a scenario OSGeo should endorse.
